Title: Closed loop bucking field system
Inventor: BENTLEY ROBERT M
IPC: H01J29/00
Filed: 1990-07-27
Granted: 1994-01-25
Abstract: Abstract of the Disclosure A system for improving the operation of a cathode ray tube (CRT)  is disclosed  whereby interference  caused  by external  magnetic  fields  is  mitigated.    The   system comprises a CRT having a CRT  magnetic shield housing  and at  least  one   electromagnetic  field  sensor   disposed adjacent to the inner surface of the CRT housing.  Sensors form  to  generate  a  reference  magnetic  field  and  to generate  a  sensor  output  signal  in  response  to  the detection of  both the  reference  field and  an  external field as sensed within the housing.  A bucking field  coil drive circuit is provided in electrical communication with the field  sensor, the  drive circuit  being operative  to generate a bucking field coil  drive signal responsive  to the field sensor output signal.   A bucking field coil  is disposed circumferentially about the CRT and is driven  by the bucking field  coil drive signal.   The bucking  field coil  generates   a  bucking   electromagnetic  field   in opposition to the sensed external magnetic field,  thereby opposing  and  reducing  the  degrading  effects  of   the external magnetic field on the CRT display.

Title: Process for the separation of sulphur oxides from offgases
Inventor: SCHOUBYE PETER
IPC: C01B17/76
Filed: 1992-05-22
Granted: 2001-02-20
Abstract: A process is provided herein for the separation of sulphur oxides from offgases. The process includes the first step of passing the sulphur oxides-containing offgas through a fixed bed of a sulphur oxide adsorbent. The sulphur oxide adsorbent has catalytic activity for the oxidation of sulphur oxides to sulphur trioxide, and comprises a mixture of vanadium pentoxide and pyrosulphates of one or more alkali metals which is supported on a porous carrier, at a temperature from 250 ° C to 400C  ° . The sulphur oxides which are adsorbed on the adsorbent are then converted to sulphur trioxide to provide a sulphur trioxide-loaded adsorbent. The sulphur trioxide-loaded adsorbent is regenerated with recirculating air at a temperature from 500° to 650°C. A part of the regeneration air is recirculated to the fixed bed of the adsorbent. Finally, desorbed sulphur trioxide in the regeneration air is removed by hydration of the desorbed sulphur trioxide to sulphuric acid, and the sulphuric acid so-formed is condensed in a sulphuric acid condenser.

Title: Pressure relief hold open apparatus
Inventor: VINCENT WILLIAM
IPC: E04B1/92
Filed: 1992-08-24
Granted: 2005-02-15
Abstract: A pressure relief panel assembly for protecting a building against over-pressure caused by explosion.      The assembly has a panel pivotally connected to a frame and held by a calibrated magnet and striker set which releases when a predetermined over-pressure occurs. A cable restraint attached to a shock absorber, or a linkage of two arms attached to a shock absorber, limits the extent to which the panel can blow open. A spring mounted on one of the arms catches the other arm when the panel has blown open, preventing the panels from re-closing and thereby preventing implosion damage to the building. Alternatively, or additionally, the panel, after opening, may be held partly open by a stop bar which pivots to prevent the panel from fully closing, to prevent implosion damage to the building after the explosion.

Title: Partial-scan built-in self-test technique
Inventor: LIN CHIH-JEN
IPC: G01R31/3185
Filed: 1992-09-28
Granted: 1997-10-07
Abstract: Testing of an integrated circuit (10), configured of a plurality of flip-flops (14 1 - 14n), at least a portion of which are arranged in a scan chain (16 1 -16k), is carried out by replacing each self-looping, non-scan chain flip-flop (14 6) with an initializable non-scan flip-flop (64). The integrated circuit (10), including each initializab1e flip-flop (64) therein, is then initialized prior to placing the integrated circuit in a non-operational mode. During the non-operational mode, a first test vector is shifted through the scan chain flip-flops, causing each to shift out a bit previously latched therein. The integrated circuit (10)) is then returned to an operational mode, after which time, a second test vector is applied to its inputs, causing a response to appear at its outputs, and also causing a bit to be shifted into each scan chain flip-flop. The response of the integrated circuit is compacted with the bits shifted from the scan chain flip-flops. By repeating this process for apredetermined number of cycles, a very high indication of the faults in the circuit can be had.

Title: Adaptive leak hdtv encoder
Inventor: KNAUER SCOTT CARROLL
IPC: H04N7/50
Filed: 1993-07-14
Granted: 1998-09-01
Abstract: An improved predictive encoder where the leak signal is a function of the buffer fullness of the encoder. More specifically, the signals stored in theencoder output buffer are further encoded based on the fullness of the buffer, and information about this further encoding is used in determining the leak factor level. In accordance with another improvement, this leak factor level is not constrained to granularity that is imposed by the decoder hardware. Removal of the constraints is accomplished by cycling through a sequence of permissible leak levels that averages at the desired level.
Patent CA-2101078-C (CA)

Granted: 2003-01-07
Abstract: The specification discloses a process for regenerating aqueous chloride leach liquors. The process involves roasting aque-ous chloride leach liquor to produce metal oxide and a gas containing HCl. The gas containing HCl is passed through a precon-centrator where it is contacted with spent aqueous chloride leach liquor. The enthalpy of the gas evaporates water from the spent liquor thereby concentrating it. At the same time the spent liquor absorbs HCl. HCl not absorbed in the preconcentrator is con-tacted with water to form hydrochloric acid. The hydrochloric acid may be mixed with the concentrated spent liquor and re-used.      Apparatus for operating the process is also disclosed.
